Who would have thought that the centuries-long debate about the shape of the Earth would lead to diss records. Yesterday, B.o.B. “Flatline” to support his theory on the Earth being flat.

Now Neil deGrasse Tyson via his rapping nephew, Tyson, has responded with their own diss track “Flat to Fact.” You read that correctly, astrophysicist Neil deGrasse Tyson is in a rap beef with B.o.B. over the shape of the Earth. Mona Scott-Young can’t produce anything this ridiculous. The best part about it is Tyson’s nephew is rapping over Drake’s Grammy-nominated track, “Back to Back.”

Do yourself a favor and listen to it below, it will make your day. Even your week.
